Absolutely. That would destroy rotation construction flexibility for the company too though, so it will never happen. The funny thing about 117 is that it is loosely based on circadian and sleep "science", but doesn't come close to recognizing how long it actually takes to fully and completely shift one's circadian cycle. If it did, we'd really have a "pilot shortage" and the public would be begging for unlimited foreigner pilot visas and cabotage and ME3 and FoC scam airlines would be on every route in the country.
